Overview

The following process converts a Buffalo Linkstation Mini (model LS-WSxxxxGL/R1) into a fully functional GNU/Linux server running Debian version 5.0.6 (Lenny) with the backported Linux kernel (version 2.6.32-27).
No disassembly required.
Here is how the process works:

Do not modify the last column of /etc/fstab... any value other than zero will cause the device to hang on startup. Basically, the system fails to detect the RAID volumes, sends the failure message to the console, waits for keyboard input (that can never arrive), and cannot respond to pings or any other network traffic. Don't find out the hard way.
